DRESS-SHIELD.

SPECIFICATION forming part of Letters Patent No. 591,981, dated October19, 1897.

Application filed March 18,1 8 9 7.

To all whom it may concern.-

Be it known that I, HENRY LEMMERMANN, a citizen of the United States,residing at Ilasbrouck Heights, in the county of Bergen and State of NewJersey, have invented a certain new and useful Improvement in Dress-Shields, of which the following is a specification.

The object of myinvention is a dress-shield which, because properlyventilated, will be comfortable to the wearer.

llcretofore attempts have been made to produce ventilatingdress-shields, sometimes by perforating the rubber or other imperviouslayer usually employed in such articles, or by perforating an absorbentmaterial inclosing the impervious layer. The first of this class ofshields was objectionable because the perspiration, against the effectsof which the shields are designed to protect the wearers garment, wouldpercolate through the ventilating-openings and damage the garment to beprotected, thus making the shield of little or no benefit to the wearer.In the second class of shields referred to, the perforation of anabsorbent fabric overlying the impervious material was of no effect as aventilator, because the impervious material, being itself unventilated,induced the same amount of heat as before.

In carrying my invention into effect, I ventilate the imperviousmaterial and protect the garment of the wearer from perspirationpercolating through by a protecting-flap located so as to loosely coverthe ventilatingholes.

In the accompanying drawings, forming a part of this specification,Figure 1 is a front view of a dress-shield embodying my invention,broken away in certain parts the better to exhibit the construction.Fig. 2 is an edge view of the layer of impervious material, showing theperforations and the flap protecting the same.

A represents the usual layer or thickness of fabric with which theimpervious layer is connected. Such a fabric layer may be em-v ployed onboth sides of the impervious layer.

B is the impervious layer, perforated by a' Serial No. 628,164. (Nomodel.)

series of small holes C, as shown. These holes are preferablyarrangedquite close together, and preferably extend across the shield and may bein successive rows. D is a protecting-flap, also of impervious material,arranged as shown, so as to cover the openings G loosely.

The form of the shield is represented in Fig. l as the conventional onenow usually employed for such articles, and the shield may be made up inany desired way, the essential feature of my invention being theimpervious material provided with a number of openings protected by aflap also of impervious material.

By this construction it will be apparent thata certain amount ofventilation will take place through the openings 0, and thereby the bodyof the wearer will be kept cooler than if such perforations did notexist, while at the same time the garment of the wearer designed to beprotected from perspiration is so protected, as the perspiration cannotstrike directly through the holes, but is, by the flap D, caused tospread out and thus be taken up by the fabric layers of the shield, itbeing understood of course that by reason of the ventilation lessperspiration and heating effect will take place than in other forms ofdress-shields.

I claim 1. A dress-shield,comprising an impervious layer havingperforations therein, and a flap also of impervious material looselycovering the said perforations, substantially as set forth.

2. A dress-shield,comprising an impervious layer having perforationstherein, and a flap also of impervious material loosely covering thesaid perforations, and a fabric covering the said impervious materials,substantially as set forth.

This specification signed and witnessed this 15th day of March, 1897.
